Solenoid latching keyed interlock sports RFID-based safety sensor

Oct. 7, 2013
The AZM300 is a combo solenoid latching keyed interlock and RFID safety sensor.

An external Maltese Cross-shaped cam lets lets the AZM300 interlock accept the actuator from any of three sides so it can mount on either left- or right-hinged doors, or sliding guards. Solenoid locking force is 1,000 N.

The interlock also has a built-in radio frequency identification (RFID) sensor to detect the actuator and indicate the guard is closed. This permits optional individual coding: The basic version of the sensor responds to any AZM300 target actuator; The “I1” version only accepts the coded ID number of a specific target actuator which is taught in during the first start-up. The “I2” version allows a repeated teach-in process for handling the possibility of a lost or damaged actuator.

The AZM300 interlock can be wired in series without degrading safety levels. Diagnostic LEDs on the sensor indicate various errors, misalignment and door open/closed signaling. For more advanced indication the AZM300 is also available with serial diagnostics.

The AZM300 housing is sealed to IP69K standards for use in hygienic or outdoors uses characterized by high temperature and high-pressure wash downs. The AZM300 also offers adjustable latching which provides a holding force of 5 or 11 lb.

The AZM300 actuator includes a dampener pad so it can double as as a door stop for small to medium-sized guard doors. Lockout/Tagout padlocks can go through the key of the actuator, preventing the guard from closing.

The AZM300 series are cULus and CE approved and can be used in the highest level of machine safety circuits, PLe to ISO13849-1 and SIL 3 to IEC61508.
